| dc.description.abstract | This study explores the potential of pulsed UV-C radiation with in the 220–280 nm spectral range for microbiological decontamination, achieved through coupling evanescent waves generated at metamaterial surfaces with incident UV-C radiation. The main objective is to assess the decontamination efficiency as a function of varying temporal intervals between UV-C pulses, while maintaining a constant pulse energy. Experiments were conducted on yeast solutions (Saccharomyces cerevisiae) used as a biological model, subjected to irradiation over different exposure durations. Optical absorption spectra revealed significant alterations in the biochemical and structural properties of the cells, correlated with the irradiation timing parameters. The findings confirm the enhanced efficiency of combining pulsed UV-C radiation with metamaterial structures for pathogen inactivation, providing a robust foundation for the development of advanced decontamination technologies in medical and industrial environments. | en |
